Answer:

76.8

Step-by-step explanation:

Using the proportion

$\frac{120}{100}$ → Percent is out of 100

$\frac{120}{100}$ = $\frac{n}{64}$ ( cross- multiply )

100n = 7680 ( divide both sides by 100 )

n = 76.8

kozerog [31]

Answer:

$r = 38584.155\,ft$

Step-by-step explanation:

The length of the trail is obtained by the definition of sine, where height is the opposite leg and length is the hypotenuse:

$\tan 11^{\textdegree} = \frac{8200\,ft-700\,ft}{r}$

The length of the trail is:

$r = 38584.155\,ft$
